Specifications

1. Install the needle case into the lower rail retainer and attach the needle case to
the retainer plate assembly. Refer to Section 3 in this manual on installing the
needle case assembly.
2. Loosen the screw under the lower rail retainer (see Figure 2-22) and push it
toward the rear to remove the play between the retainer and the lower rail of
the needle case.
Note: If you have the trimmer option, you will have to remove the grabber blade
guide assembly to access the screw.
3. When the gap between the needle case bottom rail and the embroidery head
roller bearing (see Figure 2-22) is between zero preload and .002", tighten the
screw under the lower rail retainer.
Jump Stitch Solenoid
If a jump stitch solenoid has been replaced, you may have to perform one or more
of the adjustment procedures below:
NOTE: The needle case must be removed to perform the adjustment procedures in
this section. See Section 3 for needle case removal.
Plunger Positioning
During the jump stitch solenoid replacement procedure in Section 3, you were to
count the number of threads that are showing beyond the solenoid bracket. If this
was not done, the following procedure will help position the solenoid plunger
properly. There are two plunger positions of concern:
Plunger
Position 1
The jump stitch solenoid must be positioned so that the plunger is close enough to
actuate the needle bar driver reciprocator when the solenoid is engaged (energized).
Plunger
Position 2
The plunger also must not be contacting the reciprocator during normal
embroidery, when the solenoid is relaxed or not energized.
A typical dimension for the gap between the relaxed solenoid plunger and needle
bar driver reciprocator (see Figure 2-23) is approximately 0.015 to 0.045 inches
(0.4 to 1.1 mm).
To obtain this gap, loosen the locking nut on the solenoid and rotate the solenoid
inside the bracket until the gap is proper. Tighten the locking nut.
